I forwarded Jim's message to xmission support. 207.69.200.58 is an earthlink mail delivery host: Server: 198.60.22.2 Address: 198.60.22.2#53 Non-authoritative answer: 58.200.69.207.in-addr.arpa name = pop05.mail.atl.earthlink.net. Authoritative answers can be found from: 200.69.207.in-addr.arpa nameserver = scratchy.earthlink.net. 200.69.207.in-addr.arpa nameserver = itchy.earthlink.net. itchy.earthlink.net internet address = 207.69.188.196 scratchy.earthlink.net internet address = 207.69.188.197 If lots of other earthlink users send spam through this server and earthlink doesn't do anything to stem the tide, then the server will eventually make its way onto a spam filter list. This appears to be what has happened. I've asked xmission if they can adjust the filter on their end. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>
